You sir, aren't a true nerd then!
Have been sitting at some form of desk since 1982, started with a Commodore 64. Typing lines of basic code from gaming books.
Had/still have a telnet BBS which I first had online in 1984. Started off part time with a 2400 baud modem, eventually moved up to a 28.8k... sad thing was I could tell what speed they were connecting at by the sound of the modem connection noise.
All the jobs I've had have been fixing PC's. Starting with a job where I built machines from scratch back when AT PSU's were the norm.
I've had 15 odd different cellphones, starting with an infamous Motorola brick phone all the way through to my Ideos X5 (which is getting old now but I love it). Which I like rooting and installing custom ROM's.
I've seen a few different interfaces over my lifetime, starting with a green amber screen with a flashing cursor to what we have now :-)
Even own a Mac.... which I'm ashamed to mention, although it has morphos on it. But sits under the table in the lounge gathering dust for the last 6 months. :-/
Think I still have some nerd in there :-)
